Troubleshooting
Refer to the following table to check the possible cause
and treatment for the error. If the indicated treatment does not work, turn off the power switch and contact sales
distributor or Panasonic representatives.
Note
Make sure that only qualified persons or persons who are familiar with welding machines
take case of the maintenance and inspection work.
WARNING
Touching any current-carrying parts may cause a fatal electric shock or
burn injury
To prevent a fatal accident, such as an electric shock, burn injury, etc., make sure to
observe the followings.
Make sure to turn off the power switch and the switch of the distribution box before removing the top
cover of this product.

of output signal
[01]
Current limit
The actual readout is compared to the set
value, and the actual readout is out of the set
range.
(*1)
(No detection in the case of voltage
compensation.)
At the end of
hold time
Treatment for major troubles.
(See below for details.)
[02]
Full wave
Four consecutive cycles of full wave occurred
during welding.
Treatment for minor troubles
(*2)
(Default setting) (Changeable
to the treatment for major
troubles.)
[03]
No welding
When the total of two cycles (in case of the
constant current control) and when the total of
four cycles (in case of the power voltage
compensation) of no welding occurred.
At detection
Treatment for major troubles.
1)Restart impossible.
Reset by a reset input.
2)No output of the hold end
signal.
3)Trouble output.
4)Buzzer goes off.
[04]
Welding power
error
The welding power is cut off during sequence
operation.
[05]
SCR short-circuit
Current flows during the initial squeeze time.
At the initial
squeeze time
[06]
Tip sticking
When the tip sticking function is selected, and
the both upper and lower tips are stuck to work.
At detection
[07]
CT wire cut
When the primary constant current system is
selected, and breaking of C.T. wire occurs.
When the
starting input is
turned on
[08]
Toroidal wire cut
When the secondary constant current system is
selected, and breaking of toroidal coil occurs.
[09]
Setup error
See the next section for details.
[10]
Memory error
Data that exceeds the data upper/lower limit is
stored.
When the
control power is
turned on.
[11]
Sequence stop
When the sequence stop function is selected,
and the external sequence stop input it turned
off (open).
At detection
[90]
Memory writing
error
When writing of data to memory IC is failed. (*3) At detection
1)Restart impossible.
Reset by a reset input.
2)Trouble output.
3)Buzzer goes off.
(*1) The current limit is judged by the each average value of the Weld time 1 and 2 excluding the first two cycles.
(*2) Treatment for the minor troubles includes 1) restart to reset and 2) Output of hold end signal.
(*3) The “Memory writing error” does not affect the data, such as welding condition, WELD CNTR. PROD. CNTR and
STEP UP CNTR. If the reset input does not cancel the error state, please contact Panasonic representatives.
